Problem Statement

Hi,

I have a use case where all of the auth is handled by a gateway, and access to the gateway is controlled using netpols. Problem is, Claude-code keeps looking for an auth token in the env. Is there a way to skip this check? I've tried setting:
ANTHROPIC_BEDROCK_BASE_URL=https://my-gateway/bedrock
CLAUDE_CODE_SKIP_BEDROCK_AUTH=1
CLAUDE_CODE_USE_BEDROCK=1

but still getting a 403 from claude-code.

Proposed Solution

Introduce an env var that will skip any auth token checks locally. Something like CLAUDE_CODE_USE_GATEWAY_AUTH.
